Mix dark brown sugar, rice vinegar, fish sauce, soy sauce, garlic, ginger, and red pepper flakes in a bowl. This makes the caramel sauce.
1/2 cup dark brown sugar, 1/4 cup rice vinegar, 3 tablespoons fish sauce, 2 tablespoons soy sauce, 2 cloves garlic, 1 teaspoon fresh ginger, 1/4 teaspoon red pepper flakes
Put chicken thighs in the bowl with the sauce. Let them marinate for 30 minutes to soak up the flavours.
4 chicken thighs
Warm vegetable oil in a skillet on medium-high. Take the chicken out of the marinade and put it in the skillet, skin-side down.
2 tablespoons vegetable oil
Cook the chicken for 5-6 minutes on each side. You want the skin to be crunchy and golden.
Turn the heat down and pour the leftover sauce over the chicken. Let it simmer for 10-15 more minutes. The chicken will cook through and the sauce will thicken.
Take the chicken off the heat and let it sit for a bit. This helps the taste get even better.
Add chopped green onions on top. They make the dish look and taste fresh.
